Completely Redesigned

All New FLO Wheel Line

The all new FLO Wheel line was created using a five step system that we call Data Driven Design. The result, was the fastest wheels we have ever created. Learn about each step below.

Data Logging

110,000 Data Points from Four Ironman Courses

We collected 110,000 yaw angle and relative velocity measurements by mounting a custom data logger to the front of a bike. We gathered this data on four Ironman courses, and in a variety of riding conditions. Learn more about our Data Collection Process.

Data Analysis

Yaw Angles Redefined

After analyzing our data, we learned that a cyclist experiences much shallower angles than we originally thought. We now know a cyclist spends 80% of their time riding between 0 and 10 degrees of yaw. This discovery led us to design the new FLO wheels to be fast at low yaw angles. Learn more about our Data Analysis Process.

3D Modeling

Creating a Baseline

We created a highly accurate model of the tire/rim interface, by molding a tire mounted to a FLO rim. This tire/rim model was combined with our 2012 rim profiles to create a baseline for our new design work. Learn more about our 3D Modeling Process.

Optimization Algorithm

Developed with CD-adapco Engineers

Using a list of design parameters and the data collected from our 110,000 data points, we built a custom optimization algorithm. This algorithm ran on CD-adapco's Super Computer and intelligenty tested and refined 500 prototypes to find the fastest rims shapes possible. Using a standard desktop computer, these calculations would have taken 4.5 years to complete. Learn more about our Optimization Algorithm.

The above time savings were calculated using our Net Drag Reduction Value (NDRV) equation. The NDRV equation is designed to give cyclists an accurate estimate of expected time savings using FLO wheels. Learn more about our Net Drag Reduction Value equation.
